The guy you blame for causing a loss in a sports game you should have won because:

1) He/she openly disrespected abilities of the enemy stud

2) He/she had a victory party planned before the game

3) He/she sends out an email to the office/home before the
event applauding victory
"Dave's email telling us to meet as his room after the game before it even started is why we lost! He's such a jinxster!"
